<b>Jeremy Vlcan, courtesy University of Nevada, Reno</b>Each month of the new 2013 Nevada Geology Calendar offers a stunning photo of the state's dramatic landscape, plus facts about the varied geology found around the Great Basin. This photo of sandstone in the Valley of Fire State Park in Clark County is featured in July. The official state rock, sandstone was used to build the Nevada state capitol building and the former United State Mint building in Carson City. The calendar, on sale now, was produced by one of the University of Nevada's statewide public service departments, the Nevada Bureau of Mines and Geology.
